Title: Bobbin thread cut detection device for sewing machine
Inventor: SUZUKI SHIGERU
IPC: D05B63/04
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To enable an automatic stitching operation to be performed stably without depending upon the stitch pitch or the stitching direction of a sewing machine. SOLUTION: The smallest stitch pitch Pth in a direction in which a support frame moves right before the start of a sewing machine motor is decided during a stitching operation by the start of the motor (S5), then it is checked whether the stitch pitch P of a stitch right before the start of the motor is larger than the smallest stitch pitch Pth (S6), and it is checked whether the maximum value Tmax of the tension of a bobbin thread is higher than a tension threshold value Tth, when it is P>=Pth (S7). Further, information on the presence of the bobbin thread is stored in an area for storing information on the cut of the bobbin thread, when it is Tmax>=Tth (S8) and, on the contrary, information on the non-presence of the bobbin thread is stored in the area for storing information on the cut of the bobbin thread, when it is Tmax<Tth (S9).  Besides, the sewing machine motor is stopped when the bobbin thread is not present (S12), and also the sewing machine motor is stopped when it is P<Pth (S12).

Title: Egr control device
Inventor: TSUCHIDA HIROBUMI
IPC: F02M25/07
Filed: 1992-09-22
Abstract: PURPOSE:To enhance the accuracy of diagnosing the failure of an EGR device by introducing part of intake air which bypasses a throttle valve to an EGR passage, mixing it with EGR gas, calculating the flow rate of EGR from values of gas temperature and of bypassing air flow rate measured before and after the mixing, and diagnosing the failure of the EGR device using the EGR flow rates. CONSTITUTION:Part of intake air is forced to bypass a throttle valve 45 by a bypass air passage 46 and introduced into an EGR passage 43 located downstream of an EGR valve 45, and the flow rate and temperature of the bypassing air are measured by respective measurement means 47, 48. After the bypassing air and EGR gas are mixed together the gas temperature and the EGR gas temperature are measured by respective measurement means 49, 50. The flow rate of EGR is calculated from these four measured values by an EGR flow rate calculation means 51 and when the difference between the actual and desired EGR flow rates is at or greater than a predetermined value a failure diagnostic means 52 determines that an EGR device has failed.

Title: Power circuit for memory storage
Inventor: KIMURA TSUNENORI
IPC: G06F1/00
Filed: 1985-11-12
Abstract: PURPOSE:To eliminate the need for a battery used exclusively for memory storage by obtaining the input to a power circuit for memory storage from a main body driving battery without increasing the number of batteries. CONSTITUTION:When the voltage of the main body driving battery 6 is high, the output of a voltage detecting circuit 4 is high and a TR 3 and a TR 1 turn on to operate a series regulator 1, forming a memory backup memory power source with high efficiency. The output voltage is possibly low temporarily even after the main body power source is turned off because the main body driving battery 6 flows a large current or because the remaining battery capacity becomes small. At this time, the output of the circuit 4 becomes low and a TR 2 turns on to operate a switching regulator 2, thereby supplying a backup memory voltage. In this case, the switching efficiency of the regulator 2 is extremely inferior, but the supply current is small, so the battery is nearly unloaded. The battery voltage, therefore, recovers several minutes later and the switching regulator 2 is switched to the series regulator 1, so that the current is outputted with high efficiency.
